What is an RMI?
- RMI is an abbreviation for radio magnetic indicator.
- It is an aircraft navigational instrument coupled with a gyro compass
- indicates the direction of a selected NAVAID (NDB or VOR) and indicatetes bearing with respect to the heading of the aircraft.
What is an HSI?
- The HSI (horizontal situation indicator
- combines the heading indicator with a CDI
What is RNAV?
- RNAV (area navigation)
- computing the airplane position, actual track an ground speed
- Provides: distance, time, bearing and crosstrack error relative to the selected TO or “active” waypoint and the selected route.
- Present day RNAV includes VOR/DME, an GPS systems.
What is DME
- Equipment (airborne and ground) used to measure, in nautica miles
- the slant range distance of an aircraft from the DME navigationa aid.
What is the effective range distance for DME?
- Reliable signals may be received at distances up to 199 NM at line-of-sight altitude with an accuracy of better than 1/ 2 mile or 3 percent of th distance, whichever is greater.
- Distance information received from DME equipment is SLANT RANGE distance and not actual horizontal distance.
Give a brief description of GPS
- The Global Positioning System (GPS)
- determine precise position anywhere in the world.
- A mjnimum of four satellites is necessary for receivers to establish an accurate three-dimensional position.
Can handheld GPS receivers and GPS systems certified
for VFR operations be used for IFR operations?
No, for the following reasons:
a. RAIM capability - VFR GPS receivers and all handheld units
have no RAIM alerting capability.
b. Database currency
c. Antenna location - In many VFR installations of GPS
receivers, antenna location is more a matter of convenience than
performance. In IFR installations, care is exercised to ensure
that an adequate clear view is provided for the antenna to see
satellites.
Required preflight preparations for an IFR flight using GPS for navigation should include a review of what information?
- certified for the operation.
- Verify that the databases
- GPS and WAAS NOTAMs.
- GPS RAIM availability for non-WAAS receivers.
- Review the operational status of ground-based NAVAIDs and related aircraft equipment (e.g., 30-day VOR check) appropriate to the route of flight, terminal operations, instrument approaches at the destination, and alternate airports at ETA.
- Determine that the GPS receiver operation manual or airplane flight manual supplement is on board and available for use.
How often must electronic navigation databases used
for IFR flight be updated? (
- The navigation database is updated every 28 days.
- Obstacle databases may be updated every 56 days, and terrain and airport databases are updated as needed.
Within which frequency band does the VOR equipment
operate?
VHF band - 108.00 through 117.95 MHz
What are the different methods for checking the
accuracy of VOR equipment?
a. VOT check; ±4°
b. Ground checkpoint; ±4°
c. Airborne checkpoint; ±6°
d. Dual VOR check; 4° between each other
e. Select a radial over a known ground point; ±6°
What records must be kept concerning VOR checks?
Each person making a VOR check shall enter the date, place, and
bearing error and sign the aircraft log
Where can a pilot find the location of the nearest VOT
testing stations? (
Locations of airborne check points, ground check points and VOTs
are published in the Chart Supplement U.S.
How may the course sensitivity be checked on a VOR
receiver?
- course sensitivity may be checked by recording the number of degrees of change in the course selected as you rotate the OBS to move the CDI from center to the last dot on either side.
- The course selected should not exceed 10° or 12° either side.
